{\bf \large \sf Description}\\
\hspace*{1.5cm}
\begin{minipage}[t]{13.5cm}
        Y=lambdak(U,K) evaluates the parametrization lambda function
        involved in the affine smoothed pseudo Bertrand distribution.\\

         $LAMBDAK(U,0) = -U/(exp(-U)-1)$ for K = 0
         $LAMBDAK(U,1) = exp(1+U exp(-U)/(exp(-U)-1))$ for K = 1
         $LAMBDAK(U,K) = (K (exp(-U)-1)/(exp(-KU)-1))^(1/(K-1))$ otherwise\\
